Garcia had dominated the sixth and seventh rounds to take control of the fight and picked up where he left off in the eighth. The deciding blow was a left hook to the side, which took Martinez’s legs out from under him. He failed to get up by the count of 10.

Garcia (33-0, 28 knockouts) went down in the second round but wasn’t hurt. And Martinez (27-2-2, 16 KOs) held his own boxing from the outside for five rounds.

However, Garcia began to land hard, accurate punches with great consistency in the sixth and a fading Martinez had no answer.

Garcia came in three pounds overweight for his last fight, a featherweight bout against Juan Manuel Lopez in June. The fight Saturday was his first at 130 pounds.
